Need help on creating code using cart The output has to show

Need help on creating code using cart. The output has to show multiple lines of the users information.

So far this is what I have:

index.html:

chapter8.jsp
<%@page contentType=\"text/html\" pageEncoding=\"UTF-8\"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">
        <title>JSP Page</title>
    </head>
    <body>
      <%@ page import=\"java.io.*, business.*, data.*, list.*\" %>
      <%
        // get parameters from the request
        String firstName = request.getParameter(\"firstName\");
        String lastName = request.getParameter(\"lastName\");
        String email = request.getParameter(\"email\");
        String phoneNumber = request.getParameter(\"phoneNumber\");
        // get a relative file name
       // ServletContext sc = this.getServletContext();
       // String path = sc.getRealPath(\"/WEB-INF/EmailList.txt\");

File tempdir = (File) this.getServletContext().getAttribute(\"javax.servlet.context.tempdir\");
String temppath = tempdir.toString();
String path = temppath + \"/EmailList.txt\";

        // use regular Java objects
        User1 user = new User1(firstName, lastName, email, phoneNumber);
        UserIO.add(user, path);
    %>
    <h1>Thanks for joining our email list</h1>

<p>Here is the information that you entered:</p>

    <table cellspacing=\"5\" cellpadding=\"5\" border=\"1\">
        <tr>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Email</th>
            <th>Phone Number</th>
        </tr>
        <tr>
            <td><%= user.getFirstName() %></td>
            <td><%= user.getLastName() %></td>
            <td><%= user.getEmailAddress() %></td>
            <td><%=user.getPhoneNumber() %></td>
        </tr>
    </table>
    </body>

        this.email = email;
        this.phoneNumber = phoneNumber;
    }

    public void setFirstName(String firstName)

Ans:

Cart.java:

package list;
import business;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class cart extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServeletException,IOException
   {
   PrintWriter out=response.getWriter();//creating printwriter object
   response.setContentType(\"text/html\");//setting mime type
File tempdir = (File)this.getServletContext().getAttribute(\"javax.servlet.context.tempdir\");
String temppath = tempdir.toString();
String path = temppath + \"/EmailList.txt\";
FileReader fr=new FileReader(path);//opening file read mode
BufferedReader br=new BufferedReader(fr);//to read text line by line
String temp;
out.println(\"<table border=3 align=\'center\'><tr><th colspan=4>Users Information</th></tr><tr><th>Emailid</th><th>FirstName</th><th>LastName</th><th>MobileNumber</th></tr>\");
while((temp=br.readLine())!=null)//reading text from file untill EOF has been reached
       {
String str[]=temp.split(\"|\");//spilt\'s string into 4 parts
           out.println(\"<tr>\");//opening table row
           for(int i=0;i<str.length;i++)
           {
out.println(\"<th>\"+str[i]+\"</th>\");//getting information
           }//end of for loop
           out.println(\"</tr>\");//end of table row
       }//end of while loop
       out.println(\"</table>\");
       out.close();
   }//end of doGet()
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServeletException,IOException
   {
   doGet(request,response);//redirect to doGet()
   }//doPost

}//end of cart
